ORSON MORRIS, OF RED CANYON, VVYOMING, ASSIGNOR OF ONE-HALF TO JAMES GROUTAGE, OF SAME PLACE.

MOWlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 602,586, dated April 19, 1898.

Application filed July 28, 1897. 8erial Nor 646,248. (No model.)

T all whmn it may concern:

Be it known that I, ORSON MORRIS, a citizen of the United States, residing at Red Canyon, in the county of Uinta, and State of \Vyoming,

have invented certain new and useful Improvements in Mowing-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in mowing-machines; and the object is to simplify the construction and improve the efiiciency of the machine.

To this end the invention consists in the construction, combination, and arrangement of the same, as will be hereinafter more fully described, and particularly pointed out'in the claims.

In the accompanying drawings the same reference characters indicate the same parts of the invention.

Figure 1 is a top plan view of my improved mowing-machine. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal section showing the cutter-bar elevated. Fig. 4 is a detail of one end of the pitman. Fig. 5 is a detail of the connecting-rod.

1 represents thecast frame, in which the cylindrical axle 2 is journaled, and 3 3 represent the drive-wheels fixed on the outer ends of the axle, or one of said wheels may be loosely mounted on the axle to facilitate turning curves.

4 represents a spur-gear keyed on the axle, which meshes with a pinion 5, fixed on the counter-shaft 6, which carries a spur-gear 7, meshing with a pinion 8, formed integral with the spur-gear 9 and loosely journaled on the axle. This spur-gear 9 in turn meshes with the pinion 10, fixed on one end of the crankshaft 11, journaled in the frame parallel with the axle, and the opposite end of said crankshaft carries a crank-wheel12, provided with a crank-pin 13, the outer end of which terminates in a ball-bearing head 14.

represents the pitman. Its inner threaded end is adjustably secured in the coupling 16 by means of the nuts 17 17 and the lock- 50 nuts 18 18.

The inner or opposite faces 19 of the nuts 17 17 are convex in form to snugly fit the corresponding concave sockets 20 in the coupling 16 to permit this end of the pitman to turn on its axis in the coupling. The opposite end of the coupling 16 is bifurcated and terminates in two parallel arms 21 21, formed with concave recesses 22 22 in their inner faces which form a bearing for the ball-bearing head 14 of the crank-pin 13, and they are adjustable with reference to said crank-pin by means of the transverse bolts 23 23.

24 and 25 represent integral arms extending forwardly, downwardly, and laterally from the frame 1. Located between these arms and pivoted thereto is the main shoe 26, carrying the finger-bar 28.

represents the sickle-bar having the usual reciprocating movement in the finger-bar and its inner end is provided with aright-angular stud 31, terminating in aspherical head 32, which receives the outer end of the connecting-rod 33, formed with a shell or socket 34, which snugly encompasses said head 32. to form a limited ball-and-socket joint. The opposite end of the said connecting-rod 33 also terminates in a socket 35, which encompasses the spherical head 36 of the bell-crank lever 37, fulcrumed on the stud 38, fixed in the shoe 26. The opposite arm of this bellcrank lever also terminates in a spherical head 39, which secures the encompassingsocket 40 on the outer end of the pitman 15, so that the rotary movement of the crankshaft 11 imparts a reciprocating motion to the sickle-bar.

41 represents the draft-pole or tongue extending rearwardly between the guide-flanges 42 42, and its rear end is secured to a bolt 43, fixed in the arms 44 44, formed integral with the frame 1.

45 represents a brace-lever fulcrumed on a bolt 46, fixed in the pole 41, and from one end of this lever a brace-rod 47 extends to the arm 24 of the frame, and from the opposite end of said lever a corresponding bracerod 48, provided with a turnbuckle 49, extends to the main shoe26 to preserve the alinement and prevent the finger-bar sagging backward.

50 represents a diagonal brace extending from the arm to the front end of the frame.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modifications may be made as clearly fall within the scope of myinvention without departing from the spirit thereof.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States,

1. In a mowing-machine, the combination with the main supporting-frame and cutting mechanism, the driving mechanism and a connection between the driving mechanism and the cutting mechanism, said connection comprising a pitman the rearward end of which is screw-threaded, a coupling consisting of a block having at one end a longitudinal central aperture to receive the pitman and allow it to rotate therein and prevent other movement thereof, the end walls of said longitudinal aperture being countersunk, nuts located upon said pitman and having rounded heads to fit the countersinks to afford an axial bearing for the pitman, set-nuts for locking the aforesaid nuts against longitudinal movement, thereby preventing swinging or lateral movement of the pitman with respect to the block, and means carried by the other end of the block for securing it to the driving mechanism, substantially as set forth.

2. In a mowing-machine, the combination with the main supporting-frame and cutting mechanism, the driving mechanism and a connection between the driving mechanism and the cutting mechanism, said connection comprising a pitman the rearward end of which is screw-threaded, a coupling consisting of a block having at one end a longitudinal central aperture to receive the pitman and allow it to rotate therein and prevent other movement thereof, the end walls of said longitudinal aperture being countersunk, nuts located upon said pitman and having rounded heads to fit the countersinks to afford an axial bearing for the pitman, set-nuts for locking the aforesaid nuts against longitudinal movement, thereby preventing swinging or lateral movement of the pitman with respect to the block, said block being bifurcated at its 0pposite end to form clamping-jaws, and bolts and nuts for clamping said jaws to a part of the driving mechanism, substantially as set forth.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

ORSON MORRIS.
